Abstract

A locking device for a movable carbody part has a lock and an interacting locking member. The lock has a rotary latch with pre-catch, main catch, and recess. When closing the carbody part, the locking member moves into the recess and rotates the rotary latch into a pre-catch position in which a pawl drops into the pre-catch. A motor-driven closing aid has a working lever and a control lever that are pivotably supported within the lock and have crossing slider block guides. The same slider block is guided in both slider block guides. When the working lever is pivoted by the motor of the closing aid, a shoulder of the slider block hits a counter shoulder of the rotary latch and rotates the rotary latch from the pre-catch position into a main catch position in which the pawl is supported on the main catch of the rotary latch.
